In order to analyze the labor market through search and matching theory, we need deep parameters namely, rate of inflow to the unemployment pool and job-finding rate. In other words, these rates are primary parameters of matching function; hence, estimating these parameters is an essential step for the use of search and matching theory in every economy. In this paper, we estimate these rates of...
یکی از موضوعاتی که در سالهای اخیر مورد توجه اقتصاددانان قرار گرفته است، بررسی تاثیرات نوسانات نرخ ارز بر صادرات صنعتی است. در این مقاله با استفاده از دادههای آماری سری زمانی، نقش نرخ واقعی ارز و نوسانات آن بر صادرات صنعتی کشور ایران طی سالهای 1390-1360 مورد بررسی قرار گرفته است. در برآورد الگو از ارزش افزوده و هزینه واحد کار هر واحد محصول به عنوان متغیرهای کنترل استفاده شده است. نتایج برآ...
Background : The aim of this study was to compare maintenance therapy and continuous therapy of magnesium sulfate (MS) in the management of preterm labor. Materials and Methods: In this single blind randomized control trial, 70 singleton women in 26 to 34 weeks of gestation (WG), were randomly assigned to receive 4gr MS in 200cc D/W 5% during 15 to 20 minutes either infusion therapy with 20 ...
This study uses time series data related to employment, wages, capital costs and value added to estimate labor demand function in aggregate economics in three sectors, i.e. service, industry and agriculture categorized by skilled and unskilled and in service sub-sectors. So as to anticipate economy globalization impacts on employment in the framework of three outcomes namely capital entrance, t...
This paper uncovers a counter-intuitive effect of international trade on female labor shares: whenever trade expands sectors intensive in female labor, female labor shares drop. When capital complements female labor more than male labor, the following mechanism operates: Expansions of sectors intensive in female labor come along with contractions of sectors intensive in male labor. Thus, male l...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
OBJECTIVES This study was done to compare isoxpurine hydrochloride and nifedipine as tocolytic drugs for preterm labor. METHODS A prospective cohort study of 832 antenatal women with preterm labor was conducted in the Department of Obstetrics & Gynecology. Out of 400 women found eligible for tocolysis, 200 were given isoxpurine hydrochloride while the other 200 were given nifedipine randomly....
اساس نظریه مجموعه های ناهموار، بدین صورت است که برای هر زیرمجموعه از یک مجموعه کلی، با استفاده از یک رابه هم ارزی، یک زوج مرتب از مجموعه ها را معرفی می کند. هر موفه را به ترتیب، تقریب پایینی و بالایی می نامند. تقریب پایین از یک زیرمجموعه،اجتماع تمام عناصری از مجموعه ی کلی است که کلاس هم ارزی مربوط به آن عنصر، در زیرمجموعه ی مورد نظر قرار گیرد و همچنین، تقریب بالا از آن زیرمجموعه، اجتماع تمام عن...
It is assumed in new trade theory and new economic geography that the supply of labor is fixed, which is not true in real labor markets. We develop a model of new trade theory by incorporating an elastic labor supply and analyze the impacts of technological progress on the equilibrium outcomes of working hours and economic welfare. We first show that the labor supply curve is backward bending. ...
